This flash based animation allows users to...

• Play the animation which will then loop endlessly, allowing the viewer to watch a complete cardiac cycle multiple times without stopping.
• Stop the animation at a particular frame in the animation
• Move the animation forward, or back, ONE frame each time a control button is clicked
• RESET the animation back to the first frame of the animation (atrial systole). An easy way to 'step-through' by starting at the beginning.

It also has a Tutorials pop-up menu contains links to the Cardiac Cycle Phase descriptions providing a brief summary of what is occuring in the cycle at particular points in time. Anytime the pointer moves over the TUTORIALS button, the menu appears allowing the user to select any phase tutorial.
